1035 AM CDT WED MAY 14 1986

SEVERE WEATHER AGAIN THREATENS THE SOONER STATE TODAY. STRONG
THUNDERSTORMS HAVE DEVELOPED ALREADY IN WESTERN OKLAHOMA HIS MORNING,
AND CONDITIONS ARE FAVORABLE FOR FURTHER DEVELOPMENT OF SEVERE WEATHER
OVER MUCH OF THE STATE THIS AFTERNOON AND EVENING.

A COLD FRONT THAT MOVED THROUGH MOST OF THE STATE YESTERDAY STALLED
OVERNIGHT, AND HAS BEGUN TO MOVE BACK NORTHWARD THROUGH THE STATE THIS
MORNING. VERY UNSTABLE AIR LIES SOUTH OF THE FRONT AND WILL OVERSPREAD
MUCH OF THE STATE BY THIS AFTERNOON. THE FRONT WILL COMBINE WITH A
FAIRLY STRONG UPPER LEVEL DISTURBANCE TO LIFT THE UNSTABLE AIR,
RESULTING IN THUNDERSTORMS OVERSPREADING THE STATE THROUGH TONIGHT.
SINCE THE AIR IS VERY UNSTABLE AND A LIFTING MECHANISM IS PRESENT,
THERE IS A POTENTIAL FOR SEVERE WEATHER OVER MOST OF THE STATE. CURRENT
CONDITIONS SUGGEST THE POSSIBILITY OF A SIGNIFICANT SEVERE WEATHER
OUTBREAK.

ALL INTERESTS IN OKLAHOMA ARE ADVISED TO REMAIN ALERT FOR LOCAL WEATHER
DEVELOPMENTS, REVIEW SEVERE WEATHER SAFETY RULES, AND LISTEN FOR LATER
STATEMENTS AND POSSIBLE WATCHES OR WARNINGS.

DETAILS OF THE DEVELOPING SEVERE WEATHER SITUATION WILL BE INCLUDED
IN THE OKLAHOMA THUNDERSTORM OUTLOOK TO BE ISSUED AT 300 PM. ADDITIONAL
STATEMENTS WILL BE ISSUED AS NEEDED THROUGH THE AFTERNOON IN ORDER TO
KEEP YOU ADVISED.

OKLAHOMA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE OKLAHOMA CITY OK
230 PM CDT WED MAY 14 1986

TORNADO WATCHES ARE IN EFFECT THROUGH THIS AFTERNOON OVER ALL BUT THE
EXTREME SOUTHEAST PART OF OKLAHOMA. THERE IS A MODERATE RISK OF SEVERE
THUNDERSTORMS THIS AFTERNOON AND TONIGHT OVER THE ENTIRE STATE EXCEPT
FOR THE WESTERN PANHANDLE FROM GUYMON WESTWARD.

A NEAR CLASSIC SEVERE WEATHER SITUATION IS UNFOLDING OVER OKLAHOMA,
WITH PARAMETERS COMING TOGETHER TO INDICATE THE POTENTIAL FOR A
SIGNIFICANT SEVERE WEATHER OUTBREAK THIS AFTERNOON AND EVENING. A COLD
FRONT THAT MOVED THROUGH THE STATE YESTERDAY HAS MOVED BACK NORTHWARD
AND NOW LIES ACROSS CENTRAL OKLAHOMA. WARM AND HUMID AIR LIES SOUTH
OF THE FRONT AT LOW LEVELS, WITH COOLER AND DRIER AIR ALOFT MOVING IN
ABOVE IT. THIS COMBINATION IS RESULTING IN VERY UNSTABLE AIR OVER MUCH
OF THE STATE. ALOFT, TWO DISTURBANCES ARE MOVING TOWARD THE STATE -
ONE OVER WEST TEXAS AND A SECOND OVER CENTRAL NEW MEXICO.

SEVERE WEATHER HAS DEVELOPED OVER MUCH OF CENTRAL AND NORTHERN
OKLAHOMA WHERE LIFTING OF THE UNSTABLE AIR IS BEING ACCOMPLISHED BY THE
SURFACE FRONT. OTHER SEVERE THUNDERSTORMS ARE DEVELOPING, AND ARE
LIKELY TO CONTINUE DEVELOPING, OVER WESTERN OKLAHOMA IN RESPONSE TO
THE APPROACH OF THE FIRST UPPER SYSTEM. THUNDERSTORMS WILL SPREAD
EASTWARD ACROSS THE REST OF THE STATE LATER TODAY AND WILL LIKELY
REMAIN STRONG INTO TONIGHT AS THE TWO UPPER SYSTEMS MOVE ACROSS.

THE WINDS ALOFT ARE CHARACTERIZED BY SOUTHERLY FLOW AT LOW LEVELS AND
STRONGER WESTERLY FLOW ALOFT. THIS WIND PATTERN WILL SERVE TO
DESTABILIZE THE ATMOSPHERE FURTHER, AS THE LOW LEVEL WINDS FEED MORE
WARM MOIST AIR NORTHWARD WHILE THE UPPER WINDS DRAW MORE COOL AND DRY
AIR IN ALOFT. THE WIND PATTERN ALSO IS FAVORABLE FOR THE DEVELOPMENT
OF TORNADOES.

THIS IS A DANGEROUS WEATHER SITUATION, AND ALL INTERESTS IN THE STATE
ARE URGED TO REMAIN ALERT FOR LOCAL WEATHER DEVELOPMENTS AND STAY
TUNED FOR THE LATEST WEATHER INFORMATION. REVIEW TORNADO AND SEVERE
THUNDERSTORM SAFETY RULES, AND BE PREPARED TO MOVE TO A SAFE PLACE IF
THREATENING WEATHER APPROACHES OR A WARNING IS ISSUED. SPOTTER NETWORKS
SHOULD ALREADY BE ACTIVATED AT THIS TIME OVER M7OST OF WESTERN AND
NORTHERN OKLAHOMA. THOSE IN SOUTHEASTERN OKLAHOMA WILL LIKELY BE NEEDED
BY LATE AFTERNOON.
